DETAILED DESCRIPTION

To make the technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below, in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are merely some but not all of the embodiments of the present disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the protecting scope of the present disclosure.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which present disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. As used herein, the description of “connecting” or “coupling” two or more parts together should refer to the parts being directly combined together or being combined via one or more intermediate components. In addition, terms such as “first” and “second” are only used to distinguish one element (or a part of the element) from another element (or another part of this element).

An array substrate for a display device includes a plurality of gate lines arranged in a direction parallel to the sub-pixel rows and a plurality of data lines perpendicular to the gate lines. At each side of each sub-pixel row, one gate line dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line is arranged every two sub-pixels. On such an array substrate, widths of black matrixes between adjacent sub-pixels are different, and such a phenomenon is referred to as a black matrix difference. The embodiments of the present disclosure are described by taking the above array substrate as an example. However, the protection scope of the present disclosure is not limited to the array substrate. That is, other types of array substrates may also be included.

FIG. 1 is a schematic diagram schematically illustrating black matrix difference. As shown in FIG. 1, in a row direction, a width of the black matrix at the left of a sub-pixel R is AA′, and the width of the black matrix at the right of the sub-pixel R is BB′. The black matrix of width AA′ is configured to shelter a data line, and thus its width is set according to a design rule of the black matrix. The black matrix of width BB′ is configured to shelter a common electrode, and thus its width may be adjusted within a certain range. The narrower the black matrix of width BB′ is, the greater the black matrix difference (namely, (AA′−BB′)/the width between the two sub-pixels) is in this way, the aperture ratio increases, but the brightness distribution difference between the two pixels also increases, thereby causing pixel display difference when displaying images of low gray scale. That is, a phenomenon of periodic vertical stripes (such as light and dark stripes on a white image) may occur in the case of viewing the displayed image on a screen from different distances at different angles.

FIG. 2 illustrates a schematic structural diagram of an array substrate adopting a basic pixel structure. As shown in FIG. 2, the pixel structure having the sub-pixels of the same color on different sub-pixel rows being aligned with one another is referred to as a “basic pixel structure” hereinafter. The array substrate as shown in FIG. 2 includes a plurality of gate lines 220 arranged in a direction parallel to the sub-pixel rows, a plurality of data lines 230 perpendicular to the gate lines, and a plurality of common electrodes (not shown). On the array substrate as shown in FIG. 2, at each side of each sub-pixel row, one gate line 220 dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line 230 is arranged every two sub-pixels. A first shelter 211 (namely, the black matrix of width AA′ in FIG. 1) is configured to shelter the data line 230, and thus its width is set according to a design rule of the black matrix. Whereas a second shelter 212 (namely, the black matrix of width BB′ in FIG. 1) is configured to shelter a common electrode, and thus its width may be adjusted within a certain range. As shown in FIG. 2, the first shelters 211 on different sub-pixel rows are aligned with each other, and the second shelters 212 on different sub-pixel rows are aligned with one another.

FIG. 3 illustrates a schematic structural diagram of an array substrate adopting a Bright View 3 (BV3) pixel structure. The array substrate includes a plurality of gate lines 320 arranged in a direction parallel to the sub-pixel rows, a plurality of data lines 330 perpendicular to the gate lines, and a plurality of common electrodes 350. On the array substrate, at each side of each sub-pixel row, one gate line 320 dedicated to the sub-pixel row is respectively arranged. In each sub-pixel row, one data line 330 is arranged every two sub-pixels. The common electrode 350 is positioned between the two sub-pixels. The pixel structure having the sub-pixel rows adjacent to each other as shown in FIG. 3 being arranged as deviating from each other by a half of the width of the sub-pixel, and having the sub-pixels of the same color on the sub-pixel rows arranged in one other line being aligned with one another is referred to as a “BV3 pixel structure”. The array substrate having such a structure includes a plurality of pixel groups 3000 arranged along a column direction. As shown in FIG. 3, in a BV3 pixel structure, each pixel group 3000 includes two sub-pixel rows 3100. The sub-pixel rows adjacent to each other are arranged in a staggered manner, and thus the first shelters 311 and the second shelters 312 on different sub-pixel rows 3100 are not aligned with one another. However, since each pixel group 3000 is identical in structure and aligned with one another, the first shelters 311 on the first sub-pixel row 3100 of one pixel group 3000 are aligned with the first shelters 311 on the first sub-pixel rows 3100 of other pixel groups 3000. The second shelters 312 on the first sub-pixel row 3100 of one pixel group 3000 are aligned with the second shelters 312 on the first sub-pixel rows 3100 of other pixel groups 3000. The first shelters 311 on the second sub-pixel row 3100 of one pixel group 3000 are aligned with the first shelters 311 on the second sub-pixel rows 3100 of other pixel groups 3000. The second shelters 312 on the second sub-pixel row 3100 of one pixel group 3000 are aligned with the second shelters 312 on the second sub-pixel rows 3100 of other pixel groups 3000.

The array substrate adopting the above two types of pixel structures (the basic pixel structure and the BV3 pixel structure) has the problem of pixel display difference when displaying image of low gray scale. One solution is to increase the width of the second shelter so as to reduce the black matrix difference. However, this solution may sacrifice the aperture ratio.

An embodiment of the present disclosure provides a new-type array substrate, which can avoid pixel display difference when displaying images of low gray scale, without reducing an aperture ratio. FIG. 4 illustrates a schematic structural diagram of an array substrate according to an exemplary embodiment of the present disclosure. The array substrate includes a plurality of gate lines 420 arranged in a direction parallel to the sub-pixel rows, a plurality of data lines 430 perpendicular to the gate lines, and a plurality of common electrodes (not shown). On the array substrate, at each side of each sub-pixel row, one gate line 420 dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line 430 is arranged every two sub-pixels 440. The array substrate according to the exemplary embodiment of the present disclosure includes a plurality of pixel groups 4000 arranged along a column direction. Each pixel group 4000 is identical in structure and aligned with one another. Each pixel group 4000 includes a plurality of sub-pixel rows 4100. A first shelter 411 or a second shelter 412 is arranged alternately between two adjacent sub-pixels 440 in each sub-pixel row 4100. For each pixel group 4000, the first shelters 411 on at least one of the sub-pixel rows 4100 are aligned with the second shelters 412 on at least one of another sub-pixel rows 4100. The first shelter 411 has a first width, and the second shelter 412 has a second width.

In one example, the first shelter 411 is configured to shelter a data line 430, and the second shelter 412 is configured to shelter a common electrode shown). The width of the common electrode is less than that of the data line 430, and thus the width of the second shelter 412 is less than that of the first shelter 411.

In the case that the width of the first shelter 411 is different from that of the second shelter 412, the array substrate according to the embodiments of the present disclosure can avoid, by changing the arrangement of the first shelter 411 and the second shelter 412 such that the brightness distribution difference between the pixels in a column direction is reduced, pixel display difference when displaying images of low gray scale, without reducing an aperture ratio.

Exemplary embodiments of the present disclosure will be described below with respect to different pixel structures.

FIG. 5 illustrates a schematic structural diagram of an array substrate adopting a basic pixel structure according to a first exemplary embodiment of the present disclosure. The array substrate includes a plurality of gate lines 520 arranged in a direction parallel to the sub-pixel rows, a plurality of data lines 530 perpendicular to the gate lines, and a plurality of common electrodes (not shown). On the array substrate, at each side of each sub-pixel row, one gate line 520 dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line 530 is arranged every two sub-pixels. Each pixel group 5000 includes two sub-pixel rows 5100. A first shelter 511 or a second shelter 512 is arranged alternately between two adjacent sub-pixels 540 in each sub-pixel row 5100. The first shelter 511 has a first width, and the second shelter 512 has a second width. In this embodiment, the first shelters 511 on one sub-pixel row 5100 are aligned with the second shelters 512 on the other sub-pixel row 5100, and the second shelters 512 on the sub-pixel row 5100 are aligned with the first shelters 511 on the other sub-pixel row 5100. That is, on the array substrate according to this embodiment, the first shelters 511 and the second shelters 512 are also arranged alternately in the column direction. Therefore, the number of the first shelters 511 is equal to that of the second shelters 512 in each column of shelters, thereby ensuring a uniform brightness distribution among the sub-pixel columns. Therefore, according to this embodiment, pixel display difference when displaying images of low gray scale can be avoided, without reducing an aperture ratio.

In this embodiment, the first shelter 511 is configured to shelter the data line 530. The first shelters 511 and the second shelters 512 are arranged alternately in the column direction. Therefore, on the array substrate according to this embodiment, as shown in FIG. 5, the data lines 530 has a shape like letter ‘Z’. The Z-shaped routing mode may increase a line resistance, and thus a voltage of a data signal transmitted over the data line 530 may be affected.

A second exemplary embodiment of the present disclosure provides another array substrate adopting the basic pixel structure. In the array substrate, each pixel group includes more than two sub-pixel rows. FIG. 6 illustrates a schematic structural diagram of an array substrate adopting the basic pixel structure according to the second exemplary embodiment of the present disclosure. The array substrate includes a plurality of gate lines 620 arranged in a direction parallel to the sub-pixel rows 6100, a plurality of data lines 630 perpendicular to the gate lines, and a plurality of common electrodes (not shown). On the array substrate, at each side of each sub-pixel row 6100, one gate line 620 dedicated to the sub-pixel row 6100 is arranged. In each sub-pixel row 6100, one data line 630 is arranged every two sub-pixels 640. Each pixel group 6000 may include more than two sub-pixel rows 6100. Each pixel group 6000 is divided, in the column direction, into a first pixel subgroup 600A and a second pixel subgroup 600B. The first pixel subgroup 600A may include N sub-pixel rows 6100, whereas the second pixel subgroup 600B may include M sub-pixel rows 6100. In each pixel subgroup, the first shelters 611 on different sub-pixel rows 6100 are aligned with one another, and the second shelters 612 on different sub-pixel rows 6100 are aligned with one another. The first shelters 611 on each sub-pixel row 6100 in the first pixel subgroup 600A are aligned with the second shelters 612 on each sub-pixel row 6100 in the second pixel subgroup 600B. The second shelters 612 on each sub-pixel row 6100 in the first pixel subgroup 600A are aligned with the first shelters 611 on each sub-pixel row 6100 in the second pixel subgroup 600B. In one example, the N and the M may be any value from one to four, and the N may be equal to the M.

The second exemplary embodiment is described in more detail below by taking an example in which each pixel group 6000 includes four sub-pixel rows 6100. Each pixel group 6000 is divided, in the column direction, into a first pixel subgroup 600A and a second pixel subgroup 600B. The first pixel subgroup 600A includes a first sub-pixel row 6100 and a second sub-pixel row 6100. The second pixel subgroup 600B includes a third sub-pixel row 6100 and a forth sub-pixel row 6100. In the first pixel subgroup 600A, the first shelters 611 on the first sub-pixel row 6100 and the second sub-pixel row 6100 are aligned with one another, and the second shelters 612 on the first sub-pixel row 6100 and the second sub-pixel row 6100 are aligned with one another. In the second pixel subgroup 600B, the first shelters 611 an the third sub-pixel row 6100 and the forth sub-pixel row 6100 are aligned with one another, and the second shelters 612 on the third sub-pixel row 6100 and the forth sub-pixel row 6100 are aligned with one another. Furthermore, the first shelters 611 on the first sub-pixel row 6100 and the second sub-pixel row 6100 are aligned with the second shelters 612 on the third sub-pixel row 6100 and the forth sub-pixel row 6100. The second shelters 612 on the first sub-pixel row 6100 and the second sub-pixel row 6100 are aligned with the first shelters 611 on the third sub-pixel row 6100 and the forth sub-pixel row 6100.

Adopting the arrangement according to the second exemplary embodiment may ensure a uniform brightness distribution among sub-pixel columns. Therefore, in this embodiment, pixel display difference when displaying images of low gray scale can be avoided, without reducing the aperture ratio. Because the Z-shaped routings of the data lines are reduced, in this embodiment the line resistances of the data lines can also be reduced with respect to the first exemplary embodiment.

FIG. 7 illustrates a schematic structural diagram of an array substrate adopting a BV3 pixel structure according to a third exemplary embodiment of the present disclosure. The array substrate includes a plurality of gate lines 720 arranged in a direction parallel to the sub-pixel rows, a plurality of data lines 730 perpendicular to the gate lines, and a plurality of common electrodes 750. On the array substrate, at each side of each sub-pixel row, one gate line 720 dedicated to the sub-pixel row is arranged. In each sub-pixel row, one data line 730 is arranged every two sub-pixels. The common electrode 750 is positioned between the two sub-pixels. Each pixel group 7000 includes four sub-pixel rows 7100. Each pixel group 7000 is divided, in the column direction, into a first pixel subgroup 700A and a second pixel subgroup 700B. The first pixel subgroup 700A includes sub-pixel rows 7100 on odd lines. The second pixel subgroup 700B includes sub-pixel rows 7100 on even lines. In one pixel subgroup (for example, the first pixel subgroup 700A) of the first pixel subgroup 700A and the second pixel subgroup 700B, the first shelters 711 on one sub-pixel row 7100 are aligned with the second shelters 712 on the other sub-pixel row 7100, and the second shelters 712 on the one sub-pixel row 7100 are aligned with the first shelters 711 on the other sub-pixel row 7100. In the other pixel subgroup (for example, the second pixel subgroup 700B) of the first pixel subgroup 700A and the second pixel subgroup 700B, the first shelters 711 on different sub-pixel rows 7100 are aligned with one another, and the second shelters 712 on different sub-pixel rows 7100 are aligned with one another. Such an arrangement can avoid pixel display difference when displaying images of low gray scale, without reducing the aperture ratio.

FIG. 8 is a schematic diagram illustrating a design of the array substrate as shown in FIG. 7. In order to facilitate understanding, like reference numerals refer to identical elements, parts or combination thereof in FIG. 7 and FIG. 8.

FIG. 9 is a schematic diagram illustrating a design of an array substrate adopting a BV3 pixel structure according to a fourth exemplary embodiment of the present disclosure. Each pixel group 9000 includes six sub-pixel rows 9100. Each pixel group 9000 is divided, in the column direction, into a first pixel subgroup 900A and a second pixel subgroup 900B. The first pixel subgroup 900A includes sub-pixel rows 9100 on odd lines. The second pixel subgroup 900B includes sub-pixel rows 9100 on even lines. In one pixel subgroup (for example, the second pixel subgroup 900B) of the first pixel subgroup 900A and the second pixel subgroup 900B, the first shelters 911 on the middle sub-pixel row 9100 are aligned with the second shelters 912 on the upper and lower sub-pixel rows 9100, and the second shelters 912 on the middle sub-pixel row 9100 are aligned with the first shelters 911 on the upper and lower sub-pixel rows 9100. In the other pixel subgroup (for example, the first pixel subgroup 900A) of the first pixel subgroup 900A and the second pixel subgroup 90013, the first shelters 911 on the middle sub-pixel row 9100 are aligned with the second shelters 912 on one sub-pixel row 9100 of the upper and lower sub-pixel rows 9100 and are aligned with the first shelters 911 on the other sub-pixel row 9100 of the upper and lower sub-pixel rows 9100, and the second shelters 912 on the middle sub-pixel row 9100 are aligned with the first shelters 911 on one sub-pixel row 9100 of the upper and lower sub-pixel rows 9100 and are aligned with the second shelters 912 on the other sub-pixel row 9100 of the upper and lower sub-pixel rows 9100. Compared with the design of the third exemplary embodiment, in the design of the forth exemplary embodiment, the arrangement of the first shelters 911 and the second shelters 912 are changed in both the first pixel subgroup 900A and the second pixel subgroup 900B. Therefore, pixel display difference when displaying images of low gray scale can be better avoided, without reducing the aperture ratio.

Those skilled in the art should understand that for the array substrate adopting the BV3 pixel structure, the number of the sub-pixel rows included in each pixel group may be more than six in variants or modifications of the third exemplary embodiment and the forth exemplary embodiment of the present disclosure. The variants or modifications of the arrangement of the first shelters and the second shelters based on the ideas of the present disclosure should fall in the protection scope of the present disclosure.
